Show Obsolete 4 Add an attachment proposed patch, testcase, etc. Keystrokes appear to only be registered when the trackpad is being touched. You can find lspci and dmesg output. It appears that GalliumOS, a linux distro for Chromebooks has a small one line patch that one user has reported fixes the issue. Adam, can you attach the output of dmidecode tool? Let me know if you need this output from a version of the kernel with the problem and I can reboot into a 4.

Let me know if you need me to instead revert the commit on the latest kernel source tree and recompile. I hope this is sufficient though because compiling the kernel takes a while on this chromebook, and that's currently all I have to work on for this week. Comment 13 Adam S Levy UTC I also just confirmed that keystrokes are registered only while interacting with the touchpad.

Let me know what else I can do to help. A little change in the Linux IRQ numbering which are all virtual will break this. To be honest, I'm not sure how to fix this properly. Comment 19 Mika Westerberg UTC Created attachment [details] Patch to quirk pinctrl-cherryview on Acer Chromebook Can you try if the attached patch fixes the issue for you?

I applied it to the latest kernel. I've attached dmesg output and also used the above mentioned debug kernel command line parameters. Please let me know what else I can do to help support the kernel on this platform. Feel free to reach out if you want something tested on this platform. I linked to their patch in my first post, so I assume you saw it.

Would you be willing to explain why you did not find that solution acceptable and wrote a different patch? I ask purely for my own learning. Apologies if this is not the correct forum for that.

The datasheet of that IP unfortunately I can't find a chapter about it in public documentation for Atom Z series restricts use of pins like it's described in the driver.Pins usually have fancier names than this.

You can find these in the datasheet for your chip. Notice that the core pinctrl. As you can see I enumerated the pins from 0 in the upper left corner to 63 in the lower right corner. This enumeration was arbitrarily chosen, in practice you need to think through your numbering system so that it matches the layout of registers and such things in your driver, or the code may become complicated.

You must also consider matching of offsets to the GPIO ranges that may be handled by the pin controller. For a padring with pads, as opposed to actual pins, I used an enumeration like this, walking around the edge of the chip, which seems to be industry standard too all these pads had names, too :. Many controllers need to deal with groups of pins, so the pin controller subsystem has a mechanism for enumerating groups of pins and retrieving the actual enumerated pins that are part of a certain group.

The pin control subsystem will call the. Maintaining the data structure of the groups is up to the driver, this is just a simple example - in practice you may need more entries in your group structure, for example specific register ranges associated with each group and so on. Pins can sometimes be software-configured in various ways, mostly related to their electronic properties when used as inputs or outputs. The pin configuration driver implements callbacks for changing pin configuration in the pin controller ops like this:.

The GPIO drivers may want to perform operations of various types on the same physical pins that are also registered as pin controller pins. But in some situations a cross-subsystem mapping between pins and GPIOs is needed.

Since the pin controller subsystem has its pinspace local to the pin controller we need a mapping so that the pin control subsystem can figure out which pin controller handles control of a certain GPIO pin. So this complex system has one pin controller handling two different GPIO chips. They are mapped in the global GPIO pin space at:. The above examples assume the mapping between the GPIOs and pins is linear. If the mapping is sparse or haphazard, an array of arbitrary pin numbers can be encoded in the range like this:.

When GPIO-specific functions in the pin control subsystem are called, these ranges will be used to look up the appropriate pin controller by inspecting and matching the pin to the pin ranges across all controllers.

When a pin controller handling the matching range is found, GPIO-specific functions will be called on that specific pin controller.

Chapter 5. Device Drivers

After that, the subsystem passes it on to the pin control driver, so the driver will get a pin number into its handled number range. Further it is also passed the range ID value, so that the pin controller knows which range it should deal with. Please see section 2. PINMUX, also known as padmux, ballmux, alternate functions or mission modes is a way for chip vendors producing some kind of electrical packages to use a certain physical pin ball, pad, finger, etc for multiple mutually exclusive functions, depending on the application.

This is not tetris. The game to think of is chess. Of the pins you see some will be taken by things like a few VCC and GND to feed power to the chip, and quite a few will be taken by large ports like an external memory interface.

The remaining pins will often be subject to pin multiplexing. The example 8x8 PGA package above will have pin numbers 0 through 63 assigned to its physical pins.The browser version you are using is not recommended for this site.

Thanks for your help, in any case. Possibly you need to find and install firmware for that chipset, too. Since there is no driver, the necessary firmware may not be in place, either.

Good news! Module version v5. DKMS will not replace this module. You may override by specifying --force. Adding any weak-modules.

Sorry I think misread your first post, chipset would imply that the wifi is in built; if that is the case whats the out put of:. This is the output of lspci : RTLCE But secure boot prevented this newly-built module form loading as it is not properly signed. You can also sign such modules locally with your own key — and then they will work with secure boot enabled.

This can contain some useful info in case of loading successfully and reports for any errors. After upgrading from 5. So I did as follows as usual:. Help me please. Verifying — just in case. The module was also loaded without obvious errors. We can wait a bit if the kingof13 reports the same with 5. X kernel. For the time being — until the issue with newer kernel gets resolved — you can use previous kernel where the module was working fine.

You can choose to boot into previous kernel from the boot menu when the computer starts. Dear nightromanticThanks for reminding me about older kernel selection for I overlooked this matter.Note You need to log in before you can comment on or make changes to this bug.

Is this a production system or some prototype? It doesn't happen with s2idle. The system is default to use S3 though. It's a production system. Comment 7 Mika Westerberg UTC Actually it used to save all pins but only restore those that are changed from the saved value. In this case they areand I'll attach a patch that tries to do it so you can try it out. I guess we might need a DMI based quirk to narrow the affected platforms, while, it it's possible, to submit a bug against BIOS thru vendor channels.

I would like to get the pin s which became configured differently. So, I really would like to understand a bit more about that pin s. If you know any contact in BIOS to shed a light who and why is using that pin s. What is the problem with Mika's patch? That seems like a good solution to me. If the pin is marked as gpio and is not marked as reserved by the firmware restoring the setting seems like the right thing to do to me.

I'm in favour of that one because it explains the root cause. Thank you! It it in the queue for v5.

Description Maciej Dziardziel UTC Created attachment [details] kernel config I'm trying to run ubuntu on Ryzen x with Gigabyte GA-ABgaming-3 motherboard, and it has a load of problems, starting with not being able to boot normally. During normal boot, on Following advice from various places, I've tried to: 1. Compile own kernel using 4. That gets me even further - system sees all cores now. Still only recovery mode though, but its enough to get info for this bug report.

Some observed problems: 1. Systemd cannot start journald. Perhaps because it cannot cope with amount of kernel logs? Those however are mentioned in kernel source, kernel and google are completely silent about AMDI
